This is a work-in-progress PCP Memory Mapped Value (MMV) instrumentation API in Rust.

Currently, only singleton metrics are supported. There is a simple example of it's usage at examples/physical.rs. To run it, do

cargo run --example physical

Then,

• if you have a valid PCP installation, the metrics can be monitored using the command pminfo -f mmv.physical_metrics, and the MMV file itself can be found at $PCP_TMP_DIR/mmv/physical_metrics.
• if PCP isn't installed, the MMV file will be found in /tmp/mmv/, though in order to view it you'll have compile the mmvdump tool (found here or here) and run ./mmvdump /tmp/mmv/physical_metrics.
